The events that can happen when galaxies collide are galaxies merge and galaxies triple in size.
no
I apologize for the incorrect response. When galaxies collide, the events that can happen are galaxies merge and galaxies can be disrupted or distorted due to gravitational forces. In some cases, the collision can trigger intense star formation, leading to the creation of new stars. Galaxies do not destroy their stars or disappear as a direct result of collision, and galaxies typically do not triple in size as a result of a collision.
